  1. First Read of 3D UltrasoundSupplement 43 Working Group 12 Ultrasound (3D) Joe Luszcz, Chair Pro Tem

  2. WG-12 (3D) Membership • Vendors • EBM Technologies • GE • Philips • Siemens • Clinical • AIUM / ISUOG • ASE Supp 43 First Read

  3. Goal of Supplement 43 Storage of 3D Ultrasound Volume Datasets, 2D views derived from them, and related information Supp 43 First Read

  4. Ultrasound 3D Image Types Supp 43 First Read

  5. Unique Qualities of US • Operator-dependent interactive acquisition • Separate data types in each acquisition plane • Non-image data types acquired with image • Lack of a fixed frame of reference • Different probe geometries and oblique acquisition planes • Real-time imaging at relatively high rates Supp 43 First Read

  6. 3D Ultrasound Use Cases 1 • Data-related cases • 3D Volume Data • Static and Dynamic Volume Datasets [1,2] • Suitable for rendering and slicing [3,4] • Volume calibration [5] • 2D views derived from Volume Data [6,7,8] • Static and Dynamic varieties [9] • Calibrated frame data [10] • Separation of Data Types [11] • Integrated physio waveforms with image [12] Supp 43 First Read

  7. 3D Ultrasound Use Cases 2 • Workflow-related cases • Permit Two-Step Review [13] • Frame of Reference • Frame and Probe-relative FoR • Patient-relative FoR [14,15] • Anatomical FoR (Fiducials) [16] • 3D Presentation State [17,18,19] • Key Image identification [20] • 3D spatial coordinates in SR [21] Supp 43 First Read

  8. Supplement 43 Concepts • 3D Volume Dataset represented by Enhanced US IOD • Companion Physiological Waveform IOD for related physio waveforms • Derived 2D images represented by Ultrasound Image IOD’s with backwards-compatible optional attributes Supp 43 First Read

  9. Why use existing US IOD’s? • Ease the transition for 3D ultrasound images on legacy PACS • Provide separate SOP Classes for two-stage query/retrieval • Maintain images with integrated data types for direct presentation on viewers • Defer the work of generalizing Enhanced US for 2D images Supp 43 First Read

  10. Approaches Rejected • Supplement 63 • Use of CP-337 approach for volume datasets • Use of Enhanced US IOD as 2D replacement • Oblique volume datasets (oblique views relegated to US-MF IOD) • Attempts to standardize rendering and slicing algorithms (may differ in appearance) Supp 43 First Read

  11. Questions for WG-6 • Caution note for calibration of 3D Render views? Supp 43 First Read

  12. WG-12 (3D) Next Steps • Respond to WG-6 comments by March • Prototype Implementations by mid-year • Assessing interest in public demonstration • Goal: Public Comment in August Supp 43 First Read

  13. Backup Slides

  14. US Frames of Reference Supp 43 First Read
